{"product_id":"comp-cams-gm-duramax-spring-locator","title":"COMP Cams GM Duramax Spring Locator","description":"The old standard shims will not hold up to the extreme spring pressures and high RPM in today's race engines. COMP Cams offers a simple but effective solution to this problem. These Valve Spring Locators provide a thin, hardened Steel alloy seat that will not only protect the head and shim, but also locate and hold the spring in place. Previously, this part has been available only in a cup form with the retaining portion being on the outside of the part. This required that the head be machined a great deal to accept this cup so COMP now offers an ID locator with the locating shoulder on the inside, as well as the spring cup.","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":45358583546144,"sku":"CCA4688-1","price":23.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/3126\/6848\/products\/008ce8d30aa9273effeb4be3b9583b56.jpg?v=1687494602","url":"https:\/\/mystmotorsports.com\/products\/comp-cams-gm-duramax-spring-locator","provider":"Myst Motorsports","version":"1.0","type":"link"}
